Embodiment 1

[0075] see image 3 and Figure 4 , a driving mode-based driving assistance system, which includes a single-lane driving assistance system and a multi-lane driving assistance system;

[0076] Both single-lane driving assistance systems and multi-lane driving assistance systems include data acquisition modules, HMI, intelligent driving controllers, and actuators; intelligent driving controllers control and execute according to the collected information from the data acquisition module and the function combination from the HMI. The agency executes the corresponding order;

[0077] HMI includes ADAS function on / off function setting module and setting combination module; intelligent driving controller includes reminder and warning function realization module, safety control function realization module, comfort control function realization module, and execution command generation module;

[0078] The ADAS function on / off function setting module is used to receive the driving mode...

Embodiment 2

[0089] The single-lane driving assistance system can assist the driver in driving, braking and controlling the direction of the vehicle in a single lane. The functions are classified as follows:

[0090] Reminder warning category: FCW forward collision warning, LDW lane departure warning;

[0091] Safety control functions: AEB automatic emergency braking, LKA lane keeping assist;

[0092] Comfort control functions: ACC full-speed adaptive cruise control with start and stop, TJA traffic jam assist, HWA highway assist;

[0093] FCW forward collision warning and LDW lane departure warning are implemented in the AEB automatic emergency braking and LKA lane keeping assist modules as the pre-functions of safety control functions. The above-mentioned AEB automatic emergency braking and LKA lane keeping assistance functions are realized by the safety control function module, and the ACC full-speed adaptive cruise control with start and stop, TJA traffic jam assistance, and HWA highw...

Embodiment 3

[0095]The multi-lane driving assistance system will assist the driver in driving, braking, steering or maintaining direction within the multi-lane range. Compared with the single-lane driving assistance system, the sensors of the multi-lane driving assistance system will become more abundant, and the types of functions will be multiplied. How to reasonably implement all functions during the driving process and reduce the complexity of function usage is classified as follows:

[0096] 2-a) Reminder warning: FCW forward collision warning, LDW lane departure warning, BSD blind spot monitoring, DOW door opening warning, FCTW front cross traffic warning, RCTW rear cross traffic warning, TSR traffic sign recognition;

[0097] 2-b) Safety control functions: AEB Automatic Emergency Braking, LKA Lane Keeping Assist, ELK Emergency Lane Keeping, ESA Emergency Steering Assist, FCTA Front Cross Traffic Assist, RCTA Rear Cross Traffic Assist;

[0098] 2-c) Comfort control functions: ACC fu...

Abstract

The invention discloses a driving assistance system based on a driving mode. The driving assistance system comprises a single-lane driving assistance system and / or a multi-lane driving assistance system. Each of the single-lane driving assistance system and the multi-lane driving assistance system comprises a data acquisition module, an HMI, an intelligent driving controller and an execution mechanism; the intelligent driving controller controls the execution mechanism to execute a corresponding command according to collection information transmitted by the data collection module and a function combination mode transmitted by the HMI; the HMI comprises an ADAS function opening / closing function setting module and a setting combination module; the intelligent driving controller comprises a reminding and warning function implementation module, a safety control function implementation module, a comfort control function implementation module and an execution instruction generation module. The invention further provides a driving assistance method based on the driving mode. The method can be suitable for driving habits of different drivers or fixed driving scenes in a certain period, and is very convenient to operate.

Description

technical field [0001] The invention belongs to the field of automobile safety assisted driving, and in particular relates to a driving mode-based driving assistance system and a driving assistance method. Background technique [0002] ADAS systems have been promoted on many mass-produced models. The ADAS system has gradually developed from warning, information prompt function, single-lane assisted driving to multi-lane automatic driving. The resulting system complexity increases the operational difficulty of the ADAS system. At present, the existing ADAS system has a single function classification, which cannot be applied to the driving habits of different drivers or fixed driving scenarios within a certain period of time. Therefore, we urgently need an easy-to-operate driving mode-based driving assistance system, which is suitable for different drivers' driving habits or fixed driving scenarios in a certain period of time. Contents of the invention [0003] The purpos...
